Executive Summary

Ultragenyx settled patent litigation with Navinta LLC over DOJOLVI (triheptanoin), granting Navinta a royalty-free license to market a generic version beginning January 1, 2033 (or July 1, 2033 if pediatric exclusivity is granted). The settlement removes near-term generic risk but establishes a clear generic entry date. Similar litigation against other ANDA filers remains pending.

Key Facts
